Procedures, systems, and devices for addressing quality of service (QoS) during an inter-system change of a wireless transmit/receive unit (WTRU) are discussed herein. A WTRU may send a packet data unit (PDU) modification request to a network node, such as a session management function (SMF) device, indicating support for reflective quality of services (RQoS). In response to the modification request, the WTRU may then receive an acknowledgement, after which the WTRU may then be able to send data for a PDU of a specific RQoS. The RQoS may be specific to a single PDU or a plurality of PDUs. The modification request may include Session Management (SM) and/or Mobility Management (MM) information. The modification request may be included in an attach procedure or a tracking area update (TAU).
Legal claims defining the scope of protection, as filed with the USPTO.
2. The method of claim 1, wherein the data is part of a PDU session.
3. The method of claim 1, wherein the inter-system change is part of a request that includes one or more of a Session Management (SM), Mobility Management (MM), or a tracking area update (TAU) message.
4. The method of claim 1, wherein the QCI is indicative of a specific QoS for the data.
5. The method of claim 1, wherein a PDU session was established with the 5GS network prior to the inter-system change.
7. The WTRU of claim 6, wherein the data is part of a PDU session.
8. The WTRU of claim 6, wherein the inter-system change is part of a request that includes one or more of a Session Management (SM), Mobility Management (MM), or a tracking area update (TAU) message.
9. The WTRU of claim 6, wherein the QCI is indicative of a specific QoS for the data.
10. The WTRU of claim 6, wherein a PDU session was established with the 5GS network prior to the inter-system change.
